摘要

摘要: 提出了一种利用北斗卫星导航系统（BDS）三频载波相位信号提取大变形量的单历元算法．该算法基于监测点变形前坐标,采用BDS三频信号构建的超宽巷组合利用无整周问题的数据处理策略求取变形粗略值,通过宽巷及L1原始观测值逐步精化求得精确的变形信息．采用变形监测试验平台的一组实测变形数据进行测试,验证了本文算法的可行性.

Abstract: A single epoch algorithm for extracting large deformation from BDS triple frequency carrier phase signal is proposed. Based on the pre-deformation coordinates of monitoring points, this algorithm uses BDS three-frequency signal to construct ultra-wide roadway combination, uses data processing strategy without whole-cycle problem to obtain rough deformation values, and refines the original observation walues of wide roadway and L1 to obtain accurate deformation information step by step. The feasibility of the proposed algorithm is verified by testing a set of measured deformation data on the deformation monitoring test platform.
